Electronic balance (English name: electronic balance) is a weighing instrument, which is a tool to measure the mass of an object by using Hooke's law or the lever balance principle of force. According to the structural principle, it can be divided into three categories: mechanical scale, electronic scale and electromechanical combination scale.
Electronic scale is mainly composed of three parts: bearing system (such as scale plate and scale body), force transmission and conversion system (such as lever force transmission system and sensor) and numerical indication system (such as dial and electronic display instrument).
